Abstract

Radio frequency energy harvesting (RFEH) presents a sustainable and maintenance-free solution for powering wireless sensor networks and Internet of Things (IoT) devices by converting ambient RF signals into usable electrical power. The previously leading single-band RFEH technology was limited to one frequency only, posing a risk of unproductive operation when that frequency is unavailable. This paper examines and explores the different strategy of wideband RFEH system and provides an overview of the latest advancements in wideband rectennas. The paper incorporates a comprehensive categorization of wideband rectennas that outlines the antenna type, rectifier topology, diode type, impedance matching network, and power conversion efficiency employed in each wideband rectenna design. The incorporation of a detailed table including various parametric study enriches the review with empirical data, thereby enhancing its practical significance. The discussion of design challenges, rectifier topologies, and methods to boost power conversion efficiency addresses crucial technical aspects of wideband rectifiers, filling gaps in current research literature. By combining a thorough examination of design challenges and various methodologies, the paper proves to be a valuable asset for enhancing the effectiveness and adaptability of wideband rectifiers in RFEH applications.

宽带整流天线及其设计挑战的综合综述

射频能量收集（RFEH）通过将环境射频信号转换为可用的电能，为无线传感器网络和物联网（IoT）设备供电提供了一种可持续且免维护的解决方案。之前领先的单频段RFEH技术仅局限于一个频率，当该频率不可用时，存在非生产性操作的风险。本文分析和探讨了宽带RFEH系统的不同策略，并概述了宽带天线的最新进展。本文对宽带整流天线进行了全面的分类，概述了天线类型、整流拓扑、二极管类型、阻抗匹配网络和每个宽带整流天线设计中采用的功率转换效率。纳入了包含各种参数研究的详细表格，丰富了实证数据，增强了研究的现实意义。对设计挑战、整流器拓扑结构和提高功率转换效率的方法的讨论解决了宽带整流器的关键技术问题，填补了当前研究文献中的空白。通过结合对设计挑战和各种方法的彻底检查，本文证明了在RFEH应用中提高宽带整流器的有效性和适应性的宝贵资产。

期刊介绍： The International Journal of Communication Systems provides a forum for R&D, open to researchers from all types of institutions and organisations worldwide, aimed at the increasingly important area of communication technology. The Journal''s emphasis is particularly on the issues impacting behaviour at the system, service and management levels. Published twelve times a year, it provides coverage of advances that have a significant potential to impact the immense technical and commercial opportunities in the communications sector. The International Journal of Communication Systems strives to select a balance of contributions that promotes technical innovation allied to practical relevance across the range of system types and issues. The Journal addresses both public communication systems (Telecommunication, mobile, Internet, and Cable TV) and private systems (Intranets, enterprise networks, LANs, MANs, WANs). The following key areas and issues are regularly covered: -Transmission/Switching/Distribution technologies (ATM, SDH, TCP/IP, routers, DSL, cable modems, VoD, VoIP, WDM, etc.) -System control, network/service management -Network and Internet protocols and standards -Client-server, distributed and Web-based communication systems -Broadband and multimedia systems and applications, with a focus on increased service variety and interactivity -Trials of advanced systems and services; their implementation and evaluation -Novel concepts and improvements in technique; their theoretical basis and performance analysis using measurement/testing, modelling and simulation -Performance evaluation issues and methods.
